Description

【０００１】
【発明の属する技術分野】
この発明は、段ボール等の厚紙によって形成される梱包用の緩衝体に関するものである。
【０００２】
【従来の技術】
この種の厚紙製緩衝体として、特開平１０−２４５０２８号公報において、図８に示すようなものが提案されている。この緩衝体は、底板５０の両側に、巻き込むように折り曲げて二重構造とした側壁５１を、底板５０の両端に、底板５０及び側壁５１からの延出部を重合した端壁５２をそれぞれ立設し、底板５０の周囲を対向する側壁５１及び端壁５２で取り囲んで被梱包物の嵌合凹所５３を形成し、側壁５１の頂部に、その稜線５４をずらせて先端が交互に逆方向に振れた緩衝爪５５を設けた構成とされている。
【０００３】
【発明が解決しようとする課題】
しかしながら、上記緩衝体では、落下等により被梱包物が端壁５２を押し出すような力が加わった場合、端壁５２が外側へ倒れやすいという問題がある。
【０００４】
そこで、この発明は、被梱包物を確実に保持し、各方向からの衝撃を緩和する厚紙製緩衝体を提供することを課題とする。
【０００５】
【課題を解決するための手段】
上記のような課題を解決するため、この発明に係る厚紙製緩衝体は、底板の周囲を頂部が緩衝爪により柔軟に撓む二重構造の側壁と、横受爪により外側への揺動が阻止された端壁とで取り囲んで被梱包物の嵌合凹所を形成したのである。
【０００６】
また、基本部材と取付部材とを組み合わせ、その外底板と内底板の間に支持片により間隔を設けたのである。
【０００７】
【発明の実施の形態】
この発明に係る厚紙製緩衝体は、図１及び図２にそれぞれブランク状態で示す段ボール製の基本部材１と取付部材２とから構成される。
【０００８】
図１に示す基本部材１のブランクにおいて、外底板３の両側縁には、側壁４をなす外側板５及び内側板６が順次連設されている。側壁４の中間部には、外側板５と内側板６とに跨がった複数条の切目線７が設けられ、その間の部分が緩衝爪８となっている。各緩衝爪８には、一定幅ずつ交互にずれた稜線９と、そのずれの反対側に位置する折目線１０とが設けられ、緩衝爪８の幅は、基端となる折目線１０側からその反対側へ向けてテーパ状に小さくなっている。両端の緩衝爪８の外側には、２条の折目線１１を介して外側板５及び内側板６に挟まれた頂片１２が設けられている。側壁４の両端部には、外側板５と内側板６とを繋ぐ横受爪１３が設けられ、その内縁に沿ってスリット１４が形成されている。横受爪１３には、両端及び中間に折目線１５が設けられ、中間の折目線１５は内側板６寄りに位置している。
【０００９】
内側板６の外縁の中間部には折曲片１６が、両側部には差込片１７がそれぞれ設けられ、外底板３には、その両側縁から間隔をおいて中央部に一対の差込孔１８が、両端部に各一対の差込孔１９がそれぞれ形成されている。また、外側板５から外底板３へ向けて切り込むことにより脚片２０が形成され、外側板５の中央部には取手孔２１が設けられている。
【００１０】
次に、図２に示す取付部材２のブランクにおいて、内底板２２の両側縁には支持片２３が連設され、その先端縁には差込片２４が突設されている。内底板２２の両端縁には、端壁２５をなす内端板２６及び外端板２７が順次連設され、内端板２６の内縁及び外端板２７の外縁には、内底板２２の両側縁の延長線に沿ってその外側を切り込んだスリット２８が形成されている。
【００１１】
いま、緩衝体の形成に際し、基本部材１及び取付部材２を図３及び図４に示す形態に組み立てるには、基本部材１のブランクにおいて、外側板５及び内側板６を巻き込むように折り曲げ、折曲片１６を外向きに折り曲げて外底板３に重ね、差込片１７を差込孔１９に差し込み、外底板３の両側に側壁４を立設する。この側壁４において、外側板５と内側板６との間には緩衝空間が形成され、脚片２０は外底板３から突出する。また、側壁４の頂部に並ぶ緩衝爪８の先端は交互に逆方向に振れ、横受爪１３の先端は内側へ向く。
【００１２】
また、取付部材２のブランクにおいて、起立させた内端板２６に外端板２７を重ね合わせて内底板２２の両端に端壁２５を立設し、内底板２２に対し支持板２３を下方へ折り曲げる。
【００１３】
そして、スリット１４、２８を係合させ、差込片２４を差込孔１８に差し込んで基本部材１と取付部材２とを組み合わせると、図５に示すように、内底板２２の周囲が対向する側壁４、４及び端壁２５、２５で取り囲まれた被梱包物の嵌合凹所２９が形成される。
【００１４】
この緩衝体による梱包に際しては、図６に示すように、一対の緩衝体を対向させ、その嵌合凹所２９に被梱包物３０の両端部を挿入した状態で、被梱包物３０及び緩衝体を外箱に収納する。このとき、取手孔２１に手を掛けることにより、緩衝体を被梱包物３０に引き寄せつつ、容易に外箱に収納できる。
【００１５】
このような梱包状態において、図７に示すように、外底板３と内底板２２の間には、支持板２３により緩衝空間が形成され、外底板３と外箱３１の間にも、脚片２０により緩衝空間が形成される。
【００１６】
さらに、側壁４の外側板５と内側板６の間にも緩衝空間が形成され、外側板５及び内側板６の先端部は緩衝爪８の揺動に伴い柔軟に撓む。
【００１７】
そのほか、端壁２５と外箱３１の間にも緩衝空間が形成され、落下等により被梱包物が端壁２５を押し出すような力が加わった場合にも、横受爪１３が端壁２５を受け止めて、その外側への揺動を阻止する。
【００１８】
このように、上記緩衝体を用いて梱包すると、被梱包物３０は外箱３１の内部で確実に保持され、各方向からの衝撃が緩和される。
【００１９】
【発明の効果】
以上説明したように、この発明に係る厚紙製緩衝体では、底板の周囲を頂部が緩衝爪により柔軟に撓む二重構造の側壁と、横受爪により外側への揺動が阻止された端壁とで取り囲んで被梱包物の嵌合凹所を形成したので、被梱包物は確実に保持され、各方向の衝撃から保護される。
【００２０】
また、基本部材と取付部材とを組み合わせ、その外底板と内底板の間に支持片により間隔を設けると、底方向の緩衝性が特に優れたものとなる。
